    Red propolis, composed of a mixture of resins, balsams, waxes, essential oils, and organic compounds, is known for its antibacterial, anti-inflammatory, and antioxidant properties. Sourced primarily from the northeastern coast of Brazil and produced by bees from the native plant Dalbergia ecastophyllum, red propolis was tested at different concentrations (25%, 75%, and 100%) and compared to conventional antibiotics (penicillin, gentamicin, and cefotaxime) against the bacterium Staphylococcus aureus, Escherichia coli, and Enterococcus faecalis. The results showed that red propolis exhibited significant inhibitory activity against S. aureus, E. coli, and E. faecalis, with the formation of inhibitory halos comparable to those of the tested antibiotics. However, compared to traditional antibiotics such as cefotaxime, propolis still demonstrated lower efficacy, especially against E. faecalis.
